Abstract

L'invention concerne un procédé, un dispositif, un terminal, et un serveur permettant de maintenir une connexion de communication. Le procédé est implémenté dans un terminal comprenant une application client, et comprend les étapes consistant à : établir une connexion de communication entre une application client et un serveur ; reconnaître si un paquet de données envoyé par le serveur via la connexion de communication est un paquet de données de détection utilisé pour maintenir la connexion de communication ; et, lorsqu'il est reconnu que le paquet de données est le paquet de données de détection, supprimer le paquet de données de détection. Dans les modes de réalisation de la présente invention, après qu'une connexion de communication a été établie entre une application client sur un terminal et un serveur, le serveur peut envoyer activement un paquet de données de détection au terminal de sorte à maintenir la connexion de communication. Comme le terminal n'a pas besoin de maintenir la connexion de communication établie, les ressources de calcul et la consommation électrique du terminal sont économisées, et le paquet de données de détection peut être supprimé après qu'il a été reconnu par le terminal, ce qui permet de ne pas occuper les ressources du paquet de données de détection en exécutant le traitement du paquet de données de détection.<sb />
